As one of the most professional HDD mud recycling system in China, we can design and produce mud cleaning & mixing unit with different treating capacity as 200gpm, 350gpm, 400 gpm, 500gpm, 600gpm, 800gpm, 1000gpm, 1500gpm, also we can provide customized design mud recycling system as per client’s requirement. Below is the 200gpm mud system photo we shipped recently to our HDD industry client.


The working process is as below:
The submersible slurry pump pick up the used drilling fluids from the waste pit to desilter with double deck shale shaker: the first phase is bottom deck shale shaker to separate coarse solids so that the drilling fluids can be feed to desilter cone properly. The centrifugal pump feed the clean drilling fluids to desilter cone to separate fine solids with cut point 2~5 microns, the clean drilling fluids drop down into the mud tank, the user can add powder chemicals into the venturi hopper, the mixing pump provide proper pressure to help mixing evenly. The clean fluids are ready for recycling in the mixing compartment. The mud agitator and mud gun are agitating the fluids to prevent the solids suspension in the tank bottom.


The technical configuration is as below:
1) 1 unit of GNZY753F-Y4N mud cleaner ( double deck shale shaker + desilter cone), all the shaker screen installed on the mud cleaner is composite material shaker screen, the desilter cone is 100% polyurethane material with better wear resistance material.

Last week we shipped one batch of centrifugal pump and decanter centrifuge to our Russia client, this is the repeat order from our client. The centrifugal pump is a multi function pump which can be widely used for oil and gas drilling solids control system and all the other solids and liquid separation system. In solids control system, centrifugal pump can be used as desander and desilter feeding pump, vacuum degasser jet pump, trip pump for trip tank, mixing pump, charging pump of mud pump, transfer pump.


GN brand centrifugal pump features:
1) The wear parts-impeller, pump casing is made of wear resistant material: hard ductile iron alloy,which is much stronger than grey steel, grey steel has been widely used by many other centrifugal pump manufacturers in China, it is important to know the materials to be used clearly.
2) All the pump parts are 100% interchangeable with world famous brand centrifugal pump, we can provide interchangeable spare parts for client’s old centrifugal pump
3) Mechanical seal for longer working life.
4) All bearings from FAG for reliable operation, not cheap brand bearing.
5) The skid for supporting pump and motor is made from casting instead of welding to provide reliable operation.


The decanter centrifuge will be used to treat drilling fluids, to separate the fine solids from the drilling fluids and reused to prepare for new drilling fluids for recovery. The decanter centrifuge can be installed with different speed pulley for different application, when 2200rpm pulley is used, it can be used for barite recovery, when 3200rpm pulley is used, it will be used for low gravity solids separation.
The impeller of screw is protected by tungsten carbide tiles for longer working life and repairable, the bearing is made of SKF brand, the bowl material is made of duplex stainless steel 2304.

Recently we shipped one batch of mud agitators with control panel to Middle East client. The mud agitator is installed on top of the shaker tank to stir the drilling mud and prevent it from solids precipitation. These mud agitators are installed for liquid mud plant to mix and storage drilling fluids, the user can produce the mud tanks locally to save freight cost and importation cost. The control panel is installed besides the mud agitator for convenient operation, this is GN OEM control panel with our own explosion proof certificate.


The gear box and explosion proof motor is connected directly, this is compact design to be suitable for mud tank which have limit space to install the equipments. When the client need to install their own motor to match the local explosion proof class, we will provide gearbox connected with coupler, one side is connected with gearbox shaft, one side will be connected with the client’s motor, we only need to check the installation drawing of the motor in advance to confirm the suitability. Normally we install the mud agitator on the tank every 3 meters, this is not fixed, will be varies with different drilling fluids conditions.


The mud agitator will be controlled by the control panel installed on one end of mud tank, and ON/OFF SWITCH will be installed besides the mud agitator for convenient operation, the user can control the on/off/emergency stop of the mud agitator easily when it is necessary. The mud gun will be installed to work together for agitating the drilling fluids to prevent it from sediments.
We can provide mud agitator, mud gun, centrifugal pump, mixing hopper, shale shaker, mud cleaner, vacuum degasser, desander, desilter, etc. equipments to the mud tank manufacturers locally, they can produce mud tank and use our equipments.

Recently 4 sets of solids control equipments are ready for shipment to our client, this is the repeat order from the client, they will produce 4 sets of mud tank system locally to produce sea freight cost and import tax. The configuration is as below:


1) 4 sets of shale shaker with 3 panel shaker screens, each shale shaker with 2 no vibration motors. Each shaker installed with API 170 shaker screens
2) 4 sets of 7.5KW mud agitators
3) 36 pcs of composite material frame shaker screens, dimension is 700 x 1250mm
4) 4 sets of mixing venturi hopper with stainless steel material
5) 4 sets of mud gun
6) 2 sets of centrifugal pump as mixing pump


These 4 sets of mud tank system are used for workover rig drilling mud recycling. Each mud tank with 1 unit shale shaker, 1 unit mud agitator, 1 unit mud gun, 1 unit of venture mixing hopper, 1 unit of centrifugal pump as mixing pump to drive the mixing unit. The client produce the mud tank, tank accessories, pipelines, walkways, handrails, stairs, valves, etc.


Compared with oil drilling rig solids control system, the workover rig mud tank system normally with less equipment and do not have strict requirement for the solids removal from the drilling fluids. The common rig solids control system including 2 or 3 units of shale shaker, 1 unit of mud cleaner with 2 unit of centrifugal pumps, 1 unit vacuum degasser, 1 unit of decanter centrifuge for barite recovery, 1 unit of decanter centrifuge for low gravity solids removal. Several units of mud agitator, mud guns for agitating the drilling mud, several units of mixing hopper with mixing pump, several units of charging pump to feed the drilling fluids to mud pump.
